To quickly assess the difficulty of the text, read a short excerpt:
Figure 3: The Input Device A small virtual input device icon, similar in shape to the actual input device, is shown on the virtual sheet metal piece. The icon is composed of two rectangles, which correspond to the two halves of the tool. This icon may be moved about the planes of the virtual material by the user. Operations are performed on the part at the position and orientation of this virtual icon. The system allows engineers to create parts by performing various production-like operations ...on the virtual piece of sheet metal using the tool. Tactile and spatial inputs received from the device are interpreted as function commands by the system's software. The functions available to the user are: • Bend: Pressing and holding the bend button on the input device and bending the two halves of the input device performs a bend in the sheet metal at the position and orientation of the virtual icon. The bend function is interactive; a change in the angle of the input device causes an associated change in the design representation.
